IMPROVEMENT IN CHURN-DASHER.

TQ ALL WHOM IT MAY CONOERN:

Be it known that I, J, DWIGHT KELLGG, Jr., of Northampton,` in the countyot' Hampshire, and vState of Massachusetts, have invented a newandfimproved Chuin-Dasher; and I do hereby declare that the following is a full, clear, and exact descriptionl'of the construction and operation ofthe same, referencerbeing had to the annexed drawing, making a part of this specification, in which- Figure l is a top view.

Figure 2 is an end view.`

rlhis invention relates to a new and improved form of' churn-dasher, by which the hutter can be more `quickly and easily made and gathered than in any hitherto in use, it being only necessary to rotate the dasher in one direction to make the butter, and in the reverse direction to gather it.

' In the drawings, A represents the shaft ofthe dasher, which, lying in a horizontal position, is so supported and connected with a crank or gear-wheelsoutside of the churn, that it can be rotated easily in either direction. This dasher is formed by attaching to this shaft several arms, a a1 a2, Sto., eachextending ythrough the shaft, and projecting from opposite sides ofit, and the several arms being arranged in 'a spiral manner around the shaft from end to end; and'fastening on the ends of these arms are four narrow flat strips', M M' N', the two. strips M M' running atright'anglcs to eachother, from the end'arm, a, to the centre arm a4, and the two other strips., N N', running-,in the saine manner from the centre arm, a, tothe other end arm, a7.

It will beohserved that when the strips are attached and arranged in thismanner, allfonr of'them are, at A their inner end, supported by thev central arm a, and care must-be taken so to'arrange them that the two which are attached to the same end of the arm a4, moet these at right angles, forming a `sharp point or angle, m, or n. The strips are fastened to the extreme ends of the arms, so as to present their edges to the cream as they are forced throughit.

- The operation of this improved dasher` is as follows: In turning it in the direction indicated by the arrows, the angles m n, will cut the cream-in the middle of the churn, separating itinto two portions, and generating a current towards either end of the dasher. The spiral arrangement. of the arms a al a2,'&c., will greatly assist in thi'soperation, forming a sort of double screw, which forces the currents from the centre; Meanwhile the sharp, thin strips, which are supported by the' arms, cnt easily through the cream, tending,in some degree, to increase thecurrent, but principally to operate as a bea-ter. The arms a a1 a', &c., While tending'to generate and maintain the current from the centre, do not operate thus exclusively, but in the main' serve as beaters. The joint operation ofthe rims or strips M 1I' N N and arms a al a2, 8vo., is, therefore, to induce and support',v a moderate current outward from the centre, and at the same time, if the'shaft is turned rapidly, to heat the cream thoroughly, and make the'hutter in la very short time, three minutes being all that is necessary for this ocrpose in the practical operation of'- the device. A t

i As soon as the hutter appears in the milk in sufficient quantities to show that it is thoroughly churned, the notion of the shaft is reversed, which reverses the current, throwing 'it towards the centre, and, if the dasher js turned more slowly, gathering the huttcr rapidly and thoroughly from the mill/r.

The whole operation of the dashcr is exceedingly edectivc, a'nd its'simplicity of construction. is such that -lt can be made at slight expense., and applied to any churn which will admit of a. horizontal dashe'r.

Having thus described my invention, what I claim, and desire to secure by Letters Iatent, is-

A churn-flasher, constructed with spiral rows of arms, a al al, the., and strips, M M' N N', attached to the arms, and arranged in combination with each otherand with the shaft A an'd the rows of arms, in the manner described, and for the purposes specified.
